47TH STRET AND 6TH AVENUE, 4 P.M.–“SHUT UP FOX! SHUT UP FOX! SHUT UP FOX!” Try it–it just feels good. The Code Pink Fox News Bill O’Reilly Shut-up-a-thon was proceeding brilliantly and cathartically with perhaps 2,000 people in front of Fox News HQ when Medea Benjamin, an internationally known activist, founder of Global Exchange as well as Code Pink, was suddenly arrested. A small figure wearing a pink Statue of Liberty crown, she was surrounded by police and taken into a van as the crowd chanted “Shame!” No one seemed to know why she had been targeted, besides the obvious; no one else was arrested in the largely older gathering.
